GOLF-BALL.

sPEcmmATIoN arming part of Letters Paten-t No. 736,232, dated August 11, 1903.

l Application filed February 18, 1903. Serial No. 143,984. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, CLELAND DAVIS, a lieutenant in the United States Navy, stationed -at Vashington, in the Districtof Columbia,

have invented certain new and useful Improvements in Golf-Balls, (Case I5) and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in` the art to which lo it appertains to make and'use the same.

My invention relates to improvements in golf-balls, an d it is intended to provide a golfball that will give a long and accurate flight and at the same time will be well suited for putting or approaching.

My invention will be understood by reference t0 the accompanying drawings, in which the saule parts are indicated by the same letters throughout the several views.

Figure l represents a cross-section of one form of ball constructed according to my invention. Fig.` 2 is a cross-section of another form of ball. Fig. 3 shows three of the rubber bands used in making the ball. Fig. it is a cross-sectionA of still another form of the Y ball. Fig. 5 isa detail, on an enlarged scale, of one of the rubber bands and shows the grain or iiber of the same.

The ball shown in Fig. l consists of a holgo low core A, made of a nitrocellulose compound, such as Celluloid, over which core are tightly stretched a layer B of bands of rubber and the whole is inclosed in an outer shell of gutta-percha or balata gum, preferably thelatter. In order to make the layer of rubber bands B hard and dense, atthe same time highly elastic, I construct the bands withthe grain or liber running crosswise, as indicated at h onthe band Z) of Fig. 5. Or-

` 4o dinarily rubber bands are made with the grain running longitudinally. I found from experiment that by making the grain run transversely, as shown, a much harder and more compact mass is obtainable.

In the construction of the ball the bands may be of different sizes or, as indicated at b, b', and b2, in Fig. 3, they may be made all of the same size; but I preferably employ bands of dierent sizes.

5o In the form of ball shown in Fig. 2 a solid core A, preferably of gutta-percha, is inclosed in the layer of bandsvB and the whole is incased in the shell C of gutta-percha or balata gum. In the ball shown in Fig. 4t A2 `indicates a hollow steel shell, which is hollowed out sufficiently so that the ball when completed shall be of slightly less specific gravity than water. In the same way the ball shown in Figs. l and 2 should be of a specific gravity slightly less than that of water. The purpose of this is not only to have the balls of standard weight, which is very important, but also that the balls may float in water and not be lost when a water hazard is encountered.

Having thus described my invention, what I claim, and desire to secure by Letters Patent `of the United States, is-

1. A golf-ball comprising a core, a series of rubber bands having the grain or iiber running transversely stretched thereon in the form of a hollow sphere, and an outer shell of elastic material compressed over said bands, substantially as described.

2. A golf-ball comprising a core 0f elastic material, a series of rubber-bands having the grain or fiber running transversely stretched thereon in the form of a hollow sphere, and an elastic shell compressed over said bands, substantially as described.

3. A golf-ball comprising a hollow core of elastic material, a series of rubber bands having the grain or iiber running transversely stretched thereon in the form of a hollow sphere, and an elastic shell compressed over said bands, substantially as described.

4. A golf-ball composed of a hollow core ci' elastic material having greater specific gravity than water, a series of rubber bands having the grain or fiber running transversely stretched thereon in the form Aof a hollow sphere, and an elastic shell compressed over said bands, substantially as described.

5. A golf-ball consisting of a hollow core, of a nitrocellulose compound, a series of rubber bands having the grain or liber running transversely stretched thereon in the form of a hollow sphere, andan elastic shell compressed over said bands, substantially as described.

6. A golf-ball comprising a core, a series of IOO rubber bands' having the grain or ber running transversely stretched thereaon in the form of a hollow sphere, and a shell composed of balata gum compressed 'over said rubber bands, substantially as described.

7. A golf-ball comprising a core of elastic material, a series of rubber bands having the grain or ber running transversely stretched thereon in the form of a hollow sphere, and a shell composed of balata gum compressed over said rubber bands, substantially as described.

8. A golf-ball comprising a hollow core of elastic material, a series of rubber bands having the grain or ber running transversely stretched thereon in the form of a hollow sphere, and a shell composed of balata gum compressed over said rubber bands, substantially as described.

9. A golf-ball composed of a hollow core of elastic material having a greater specific gravity than water, a series of rubber bands having the grain or ber running transversely stretched thereon in the form of a hollow sphere, and a shell composed of balata gum compressed over said rubber bands, substantially as described.

10. A golf-ball consisting of a hollow core,

of a nitrocellulose compound, a series of rubber bands having the grain or ber running transverselyr stretched thereon in the form of a hollow sphere, and a shell composed of baY lata gum compressed over said rubber bands, substantially as described. Y

ll. A golf-ball havinga core of molded elastic material of spherical shape, from which a portion or portions are omitted or removed, a series of rubber bands having the grain or ber running transversely stretched on said core, and a shell of hard elastic material compressed over said series of rubber bands, substantially as described.

12. A golf-ball havinga core of molded elastic material of spherical shape, from which a portion or portions are omitted or removed, a series of rubber bands having the grain or ber running transversely stretched on said core, and an outer shell composed of balata gum compressed over said rubber bands, substantially as described.

In testimony whereof I afX my signature in presence of two witnesses.

CLELAND DAVIS.
